Why do regulated SMEs and boutique practices look for Microsoft Purview alternatives?

Microsoft Purview Data Loss Prevention (DLP) requires top-tier Microsoft 365 E5 or E5 Compliance add-on licensing (typically adding £40+ per user per month). Furthermore, setting up Purview sensitivity labels, classifiers, and Azure DLP rules requires specialized IT consulting and weeks of maintenance. Smaller regulated firms want a lightweight, direct solution that protects AI prompts in workstation RAM without complex cloud policy configurations.

Does Purview protect unredacted prompts sent to web AI tools like ChatGPT or Claude?

Purview DLP relies heavily on endpoint blocking or warning notifications that interrupt staff workflows. Fee earners frequently bypass blocks by rephrasing or copying matter data into browser tabs. OmitPII solves this by sitting directly between the user and external AI: it automatically cleans names, figures, and confidential records in local RAM before dispatch, allowing staff to get productive work done without leaking data.

Can OmitPII run alongside existing Microsoft 365 Business deployments?

Yes. OmitPII runs on Windows 10/11 alongside Microsoft 365 Business Standard or Business Premium without requiring any changes to your Microsoft tenant or Azure configuration.
